Conifer- grow cones Deciduous- drop leaves during winter Evergreen- stay green all year

Which of these two are opposites???

Hardwood that it grows flowers, like the cherry blossom tree.

Hardwood trees have broad leaves and are usually deciduous. Its seeds have some kind of covering - an apple tree hides its seeds in an apple, and an oak tree hides its seeds in an acorn.

Softwood means it is coniferous. Instead of growing flowers, it grows cones,

like the pine tree! And instead of broad leaves, it usually

grows needles on its branches. Its seeds have no covering, and just fall to the ground to grow a new tree.

The terms "softwood" and "hardwood" aren't complete nonsense though – softwoods tend have softer wood than hardwoods, but it just isn't always true.

Needlelike

Scalelike

Unique in that the leaves are narrow in width and quite long in length.

Needle length differs among tree species

Helps with Tree Identification

Single- 1 needle per node

Group- 2-5 needles per node

Cluster- 5 or more needles per node

The shape consists of overlapping leaves which look like scales
